"Not So Different"
In Raiders of the Lost Ark, rival archaeologist Rene Belloq provides a definitive example of this trope when he taunts the protagonist, Indiana Jones.
"You and I are very much alike. Archeology is our religion, yet we have both fallen from the pure faith. Our methods have not differed as much as you pretend. I am but a shadowy reflection of you. It would take only a nudge to make you like me. To push you out of the light."
TV Tropes has page after page on nothing but these hackneyed phrases.
